Hello there, I'm Tobias Alfers

Psychometrician & Full Stack Developer

💡 As a Psychometrician, I specialize in designing, developing, and implementing tools for psychological assessment. I have developed a strong expertise in Item Response Theory (IRT).

💻 As a Web Developer and Statistical Programmer, I bring the same analytical rigor to code. I'm experienced in a range of programming languages and technologies, with a special love for Julia. I enjoy building sleek, user-friendly websites and applications that are not only visually appealing but also backed by solid, efficient code.

🔍 I'm always exploring the intersection between psychometrics and web development, and I love the challenge of integrating complex psychometric principles into web-based applications.

📫 If you'd like to get in touch or discuss potential projects, please feel free to reach out via email at tobias@alfers.eu or connect with me on LinkedIn.
